It's going to take a lot more than a few sweeps per channel to achieve that, and so far, no one that I know of has been willing to put out a room correction that actually goes all the way and finishes the job.
Hm. I kind of disagree. In fact, I disagree rather vehemently.
A house is not a sound studio. If one's house does look like a sound studio, chances are they've never been married, will never be married, wear very unattractive clothes (regardless of price) and take only occasional showers.
Having established this, what is the alternative?
The alternative is DRC. At least my experience has been more than positive.
My house is generally acoustically live. Very live. Stone floors in the main areas and hardwood in my TV room, with lots of floor-to-ceiling glass and bare walls. All sorts of stuff bounces around and sometimes even the rafters shake, on things like Portishead. I hate rafters shaking.
So, a few years ago I replaced my subs with subs with built-in EQ and the improvement was immediately noticeable.
Later I tried adding a receiver with Audyssey MultiEQ XT and it provided some additional improvement, although admittedly minimal. In any case, using the sub EQ (and Audyssey) was definitely better than no EQ.
Finally, I got an R-972 on a whim (it's dirt-cheap at the closeout prices) and Trinnov Optimizer turned out to be the best acoustic improvement in my house since I first added a subwoofer. It's really that good, at least in my TV room (in the LR I don't use Trinnov, but ran the sub's EQ, then measured and tweaked it manually). But Trinnov does some amazing stuff with multi-channel.
So, do I think electronic correction is futile? Absolutely not!
Of course, your mileage may vary and some implementations are better or worse than others. Some possible worse than no EQ, I suppose.
But from what I've heard, Room EQ is the future and probably the most promising home audio improvement to come in decades.
